Abstract

Indonesia's increasing demand for Liquefied Petroleum Gas (LPG) – projected to reach 13.2 million tonnes by 2050 – and its heavy dependence on imports, require alternative and sustainable fuel solutions. Among the options under development, researchers and industry stakeholders consider Dimethyl Ether (DME)—particularly from abundant domestic low-rank coal—a viable and strategic substitute. DME has physicochemical properties similar to LPG, as well as its compatibility with existing storage and distribution infrastructure. This comprehensive study evaluates the techno-economic aspects of replacing LPG with coal-based DME in the household sector. The factors analyzed include energy equity, production and distribution costs, and projected fiscal impacts on the national economy. Assuming a production capacity of 1.4 million tons per year and an Internal Rate of Return (IRR) of 12%, analysts estimate DME’s Free-On-Board (FOB) price at IDR 8.03 million per ton, with a benchmark price equivalent to LPG at IDR 16,666/kg. At this rate, replacing imported LPG with domestic DME can save the country's foreign exchange around IDR10.71 trillion per year, but has the potential to increase subsidies by IDR3.97 trillion. The government can use the foreign exchange savings to cover the potential increase in DME subsidies.

Abstract

Diesel engines have long been the primary choice across various industrial sectors, including agricultural transport vehicles. However, energy efficiency and fuel consumption remain significant challenges. One approach to address these issues is the application of Ultra Fine Bubble (UFB) technology to diesel fuel, which aims to enhance physical fuel properties and improve combustion efficiency. This study was conducted to evaluate the effect of UFB treatment on B0 CN-51 and B40 fuels in relation to fuel quality and diesel engine performance. The fuel characterization tests showed that the calorific value of B0 CN-51 increased from 43.73 MJ/kg to 45.68 MJ/kg, and B40 from 42.46 MJ/kg to 42.94 MJ/kg. The cetane number also increased, accompanied by a reduction in sulfur content and lubricity. Performance testing using a chassis dynamometer indicated improvements in maximum power and torque. B0 CN-51 UFB produced 95.68 kW of power and 344.18 Nm of torque, while reducing specific fuel consumption (SFC) from 42.25 to 39.82 g/kWh. In addition, fuel consumption in ℓ/100 km decreased significantly, with an average reduction in efficiency of up to 4.85%. For B40, SFC decreased from 44.99 to 43.75 g/kWh, with an average consumption reduction of 1.73%. These results demonstrated that UFB can significantly improve diesel engine performance and fuel efficiency.
